What is bee bread made of?

Bee bread is a nutrient-rich substance created by honeybees as a food source for their brood (larvae). The correct answer highlights that bee bread is made from a combination of pollen and nectar. When bees collect pollen from flowers, they mix it with nectar, which adds moisture and sugars. This mixture is then packed into the cells of the hive and fermented, allowing it to develop additional beneficial properties, including increased digestibility and nutritional value.

The combination of pollen, which is high in protein, vitamins, and minerals, with nectar, which provides carbohydrates, creates a balanced food source essential for the growth and development of young bees. None of the other options capture this vital combination. For instance, pollen alone would not provide the necessary moisture and energy that nectar contributes, and while honey does contain sugars, it is not combined with nectar in the same way as bee bread is.
